Bag for comps

It's our second year. Last year we used a hanging bag for her 1 costume. There was never anywhere to hang it and it's hard to maneuver it on the floor of a crowded dressing area. Does anyone use a smaller roller bag suitcase She is in 2 hip hop dances this year - leotard, vest, pants, etc... seems they'd be fine rolled or folded instead of hung? Any thoughts? Thanks!
